Mapoinzi mana aunofanira kutarisisa paunenge uchishandisa RCBO

Kana zvasvika pakuchengetedzeka kwemagetsi, kukosha kwekushandisaRCBO (Chinosara cheDunhu reMazuva Ano chine Dziviriro yeMazuva Ano) hazvigone kutaurwa zvakanyanya. Chishandiso ichi chakakosha chakagadzirirwa kuchengetedza vashandi kubva mukuvhunduka kwemagetsi kana michina ikatadza kubuda, zvichiita kuti pave nekuchengetedzeka kwevanhu munzvimbo dzekugara nedzekutengeserana. Nekuwanda kwayo uye kuchengetedza ma "short circuit", maRCBO zvinhu zvakakosha mune chero sisitimu yemagetsi. Zvisinei, pane zvinhu zvakakosha zvekurangarira kana uchishandisa RCBO kuti ive nechokwadi chekuti inoshanda zvakanaka uye inoshanda zvakanaka.

Chekutanga, zvakakosha kutarisisa kukosha kweRCBO. Kana chidziviriro chekushanda chereductive current chakaiswa pakati pekudzivirira kwakajairika nekudzivirira kwekupedzisira, kukosha kwacho kwereductive current kunofanirwa kunge kuri pakati pekudzivirira kwereductive current yepamusoro nepasi. Musiyano wematanho unofanirwa kunge uri pakati pe1.2 ne2.5 nguva kuti uve nechokwadi chekuti RCBO inoshanda zvakanaka uye inoshanda zvakanaka mukati memagetsi.

Pamusoro pehuwandu hwemagetsi ekushanda hwakatarwa, zvakakoshawo kufunga nezvehuwandu hwemagetsi ekushanda hwakatarwa hwehudziviriro hwese. Munguva isiri yemvura, huwandu hwemagetsi ekushanda hwakatarwa hahufanirwe kudarika 75-100mA, uye munguva yemvura, hahufanirwe kudarika 200-300mA. Pamashandisirwo epamba, huwandu hwemagetsi ekushanda hwehudziviriro hwemagetsi ekushanda hahufanirwe kupfuura 30mA kuti hupe dziviriro yakananga kuvanhu. Pamusoro pezvo, kana RCBO ichishandiswa pamidziyo yemagetsi inofambiswa nemidziyo yemagetsi yenguva pfupi, huwandu hwayo hwemagetsi hunofanirawo kuva 30mA.

Chimwe chinhu chakakosha chekufunga nezvacho pakushandisa RCBO ndechekuisa nekusimbisa michina zvakanaka. Kuti pave nekuchengetedzwa kwemagrid emagetsi ane voltage shoma, nzvimbo isina kusimba yetransformer inofanira kunge yakabatana zvakananga nepasi. Zvakakosha kuve nechokwadi chekuti grid neutral conductor haina kusimba kaviri uye inochengetedza insulation level yakafanana neye phase conductors. Pamusoro pezvo, nzira yekuisa residual current action protector inofanira kudzivirira neutral line nephase line kuti isagovaniswe nemamwe macircuit kuti ive nechokwadi chekuti RCBO inoshanda zvakanaka.

Chekupedzisira, kugoverwa kwemutoro wemagetsi kunofanirwa kufungwa nezvako pakushandisa RCBO, kunyanya mitoro yechikamu chimwe chete. Zvakakosha kugovera mwenje nemimwe mitoro yemagetsi yechikamu chimwe chete zvakaenzana pamitsetse yemagetsi yechikamu chimwe chete. Kana kutsauka kuri kukuru, zvigadziriso zvinofanirwa kuitwa kuti magetsi ekubuda kwechikamu chimwe nechimwe aenzane kuitira kuti RCBO ishande zvakanaka. Pamusoro pezvo, kana mitsetse yemagetsi yakaderera iri mitsetse yenzvimbo, zvikamu zvitatu izvi zvinofanirwa kunge zvakaenzana kuti zvipe kugoverwa kwakaringana kwemutoro wemagetsi.

Muchidimbu, kushandiswa nemazvo kweRCBOs kwakakosha pakuchengetedza nekudzivirira magetsi. Nekuteerera kukosha kwekushanda kwemagetsi kwakarongwa, simba rekushanda rakarongwa, kuiswa nepasi, uye kugoverwa kwemidziyo yemagetsi, vanhu vanogona kuve nechokwadi chekuti RCBO inoshanda zvakanaka mumagetsi avo. Nekukwanisa kwavo kudzivirira kubva mukuvhunduka kwemagetsi uye kutadza kwemidziyo, maRCBOs chikamu chakakosha mukuchengetedza zvivakwa zvemagetsi zvakachengeteka uye zvakavimbika.
